870449 ÷ 12 
The aim is to understand the frequency of 12 in 870449.

Going ahead to step 1:
The number 12 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 12

Let's proceed to step 2:
If we divide 87 by 12, we get 7 and a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 84 from 87 to get 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 12

Going ahead to step 3:
12 goes into 30 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 72.0
The remainder is 6 after subtracting 24 from 30.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 12

Let's proceed to step 4:
If we divide 64 by 12, we get 5 and a remainder of 4.
The next digit of our result is 5. 
Result so far: 725.0
Deduct 60 from 64 and we're left with 4.
Fetch the next digit (4) from the dividend, attach it to 4 and continue: 44 / 12

Step 5:
When dividing 44 by 12, we get 3 with a remainder of 8.
Use 3 as the next digit of our solution. 
Result so far: 7253.0
If we subtract 36 from 44, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

On to step 6:
When dividing 89 by 12, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 72537.0
Subtracting 84 from 89 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
12 can be fit into 50 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 72537.4
Subtract 48 from 50 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 8:
12 goes into 20 1 times with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 72537.41
If we subtract 12 from 20, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 72537.416
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
12 goes into 80 6 times with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 72537.4166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 72537.4166 with a remaining 8e-05.
